Defensive publication

ABSTRACT

THIS INVENTION RELATES TO POLYOLEFIN/GLASS FIBER COMPOSITIONS CONTAINING GLASS FIBER WHICH HAVE BEEN TREATED WITH AN ANIONIC OR NONALKALI EMULSION OF A MODIFIED POLYOLEFIN. THESE COMPOSITIONS FORM MOLDED OBJECTS HAVING SIGNIFICANTLY HIGHER TENSILE STRENGTHS AND HEAT-DISTORTION TEMPERATURES AND ARE MORE HYDROLYTICALLY STABLE THAN SIMILAR MOLDED ARTICLES MADE WITH GLASS FIBER COATED WITH AN ALKALI-CONTAINING EMULSION OF A MODIFIED POLYOLEFIN.

DEFENSIVE PUBLICATION UNITED STATES PATENT OFFICE Published at the request of the applicant or owner in accordance with the Notice of Dec. 16, 1969, 869 0.G. 687. The abstracts of Defensive Publication applications are identified by distinctly numbered series and are arranged chronologically.

Filed Apr. 2, 1973, Ser. No. 347,003 Int. Cl. C08f 45/10 US. Cl. 260-41 AG No Drawing. 15 Pages Specification This invention relates to polyolefin/ glass fiber compositions containing glass fiber which have been treated with an anionic or nonalkali emulsion of a modified polyolefin. These compositions form molded objects having significantly higher tensile strengths and heat-distortion temperatures and are more hydrolytically stable than similar molded articles made with glass fiber coated with an alkali-containing emulsion of a modified polyolefin.
